The site-selective doping of dyes into spin-cast thin films with different phase separation structures of polystyrene-block-poly(4-vinyl pyridine) (PS-b-P4VP) diblock copolymers and the dopant-induced laser ablation of the dye-doped films fabricated were investigated. The selective doping of dyes into P4VP parts was carried out by immersing the films in a methanol solution containing the dyes, in which the driving force was induced by hydrogen bonds between the nitrogen atoms of pyridyl groups and the carboxylic groups of the dyes. Schematic models for the adsorption process of the dyes in the methanol solution were discussed. Dopant-induced laser ablation was carried out on the dye-doped block copolymer films, resulting in the ablation of dye-doped P4VP parts only. Factors affecting selective ablation, such as dyes, the morphologies of phase separation structures, the number-average molecular weights of the diblock copolymers, and irradiation environments, were discussed.
